To ZZ 'whom may concern Ile itv known that l, `Tetonas Pon'rnn Anuman, acitizen oit the United States, re-

-. siding at Detroit, in the county'oi Wayne and State of Michigan, haveinvented certain nenv and useful Improvements in Frank-HandleAssemblies, of which the following is a specification.

This invention relates to crank handles and has 'lor its object a crankhandle assembly of such a character that the escutcheon may have aneccentric configuration.

The invention is particularly designed in connection with the ornamentalhandles used for operating window regulators inl closed automobilebodies.' It is the lobject of the invention to provide a crank handleassembly which includes the escutcheon which may be secured to theWindow regulator case simply by a turning movement, preferably byscrewing. lHoWever, the escutcheon is so arranged with this assemblythat the saine may be positioned at any point in the 360 degrees that isrequired by the special configuration of the escutcheon. This Will bemore-fully explained hereinafter. p w

In the drawings:

Fig. 1 is an elevation of the crank handle.

Fig. 2 is an elevation partly in section taken at a 90 degree point fromthe showing in Fig. l. I

Fig. 3 is a view similar to Fig. 2 showing how the crank handle caribeconnected up with the escutcheon thimble to screw into the threadedsocket of theregulator casing;

Fi 4 is a side elevation of the cran hand e.

The ornamental crank handle is designated a. This is provided with a hubb and Where the handle is made of brass, the end of the hub may befeathered as at o and spun over against theshoulder in the escutcheonthimble d. Or the thimble might be cast upon the hub of the handle wlthan intervening coating of plumbago Aand sour milk or other binder. Theinner end of the escutcheon thimble is externally threaded as at e Whilethe outer endr is shouldered as at f to receive the escutcheon plate g,which is preferably provided with an ornamental pattern. This eseutcheonplate is not symmetrical in the sense that all parts have a definitesymmetrical position with respect to the center of the plate.

here shown, it is more in the torni of a shield. The consequence is thatin order to give a proper appearance this escutcheon plate mustI alwaysoccupy a definite position in the interior of the car. such a pattern asis here shown it is desirable to have the shield in correct verticalposition.

the car the shoulder and the contacting portion of the tace of theescutcheon join in one substantial continuous place so as to almostobscure any appearance of division here.

This is made possible by a special form of wrenchhold that is party ofmy inven- For instance, in

New, obviously were the shield 'and escutcheon thimble one single piece,thls tif) tion.` If the escutcheon thimble were provided with the usual.hexagon Wrench hold the fixture would have more of the appearance of avmechanical structure rather than an ornamental one,.such as intended.The

into the socket by providing 7 hal-f a keyhole j in theescutcheonthimble and' half a key-hole 1c inthe underside of the crank4 handlenear the point Where it merges into the hub. These tw'o" holes lmaybelined up and a pin or tool z' placed in the holes. This serves totemporarily key the crank handle to the escutcheon thimble.`'IYhereuponfthe f crank handle can be used as a Wrench to turn thethimble in its socket The tool may then be removed and the crank handlecan" then bey revolved freely in the thimble.

What I claim is:

LA crank handle assembly, having inv combination with a base providedwith a socket, an eseutcheon thimble, a crank proy vided with a hubpermanently locked rotatably into the escutcheon thimble before assemblyonto the support, and an escutcheon plate having an irregularconguration requiringa predetermined location in rotation and rotatablymounted upon the escutcheon thimble.

2. .A crank handle assembly, having in combination with a base providedwith a Socket having internal threads, an escutcheon thimble providedwith vexternal threads adapted to screw. into the threads of the socket,a crank handle provided with a hub prmanently locked rotatably in thethimble fore-assembly onto the sup ort, and an `irregular escutcheonplate having a desi' requiring a predetermined location in its rotationand rotatably supported on the outside of the thimble. l 3. A crankhandle assembly, the combination with a base provided with an internallyternal threads on its linner ends, a crank handle and hub lockedrotatably in the thimble, the said crank handle and outer end of thethimble provided with holes that may be brought in to reglist for theinsertion of -a too to key the an e and the thimble together to rotatethe thimble into its socket.

4. A'handle assembly, having in combination a base provided with-asocket, an externally shoulderedv thimble adapted to turn into saidsocket for support, an escutcheon late rotatabl su ported' onsaid'thimble hind said Y oul er, a crank handle and hub locked rotatablsin said thimble, the outer end of the t 'unble and the crank handleAbeing providedv with registerable threaded socket, ofa thimble havingex;

holes, by which aftool maybe inserted. to 40 turn the thimble into itssocket.

vIn testimony whereof'I have ed my signature.
